"The current research on IBD overturns years of established thinking. We now know that the foods you eat DO play a role in your IBD. This is great news for IBD patients and their families, because therapeutic diets add another proven treatment to our toolkit."

What is Dietary Therapy?

In a nutshell, dietary therapy for Inflammatory Bowel Disease (IBD) is a way of alleviating symptoms and inducing remission using specific nutrient dense foods and excluding certain other foods. There are an increasing number of different dietary therapies with growing bodies of research to support them. While we haven’t proven exactly why they work, the evidence suggests that they do work for many patients.

For many individuals, dietary therapy is a critical piece of a treatment protocol that may also involve medication. For others, dietary therapy can work on its own. And for some, dietary therapy may not work as part of their therapy regimen.

What is the Theory Behind Dietary Therapy?

We know that the development of Inflammatory Bowel Disease, including Crohn's Disease and Ulcerative Colitis, is complex. It involves the interplay between many factors, including a person’s microbiome (gut microbes), their immune system, their genes, and their environment. In the past, experts did not consider diet to play a role in IBD, but evolving research is showing otherwise.
   Studies on therapeutic diets for IBD suggest that specific changes in diet can promote healing by reducing inflammation. The exact mechanism of how this works is still unclear, but researchers think that the anti-inflammatory effect may arise when the diet alters a person’s microbiome.
   Since both the painful symptoms of IBD and the progression of the disease are driven by inflammation, reducing inflammation with therapeutic diets can alleviate symptoms and even induce remission for some individuals.

The Development of Nutrition Therapy for IBD

The most well-established exclusion dietary therapy for pediatric Crohn’s Disease (CD) is exclusive enteral nutrition (EEN) (Konstantinos, G et al). Patients on EEN consume liquid formula-based supplements as their sole nutrient source for an average period of 8 weeks. This dietary therapy has been found to induce disease remission in pediatric patients (Lee, D et al) and the evidence is clear. It produces a similar remission rate to patients on corticosteroids, with better intestinal healing (Borrelli, O et al). EEN has been used for over a decade as a primary means of disease treatment in Europe. These same results have not been found for adults, and researchers think this may be because the liquid diet is challenging for adults to adhere to.

Since the establishment of EEN as nutrition therapy for IBD, researchers have built a body of evidence supporting the use of several different therapeutic diets. These diets share some commonalities in the foods they eliminate, but they differ widely in other respects.

Currently, some of the better-known therapeutic diets in the literature include the specific carbohydrate diet (SCD), the modified SCD, the Anti-inflammatory diet for IBD (IBD-AID), the Auto-Immune Protocol Diet (AIP) and the Crohn’s Disease Exclusion Diet (CDED). Each of these therapies is backed by varying types of research and participant numbers. For more in-depth information on these various therapeutic diets, this site is an excellent resource.

Dietary therapy is best supported by a multidisciplinary team including GI doctor, trained dietitian, and mental health provider.

Which Dietary Therapy is the Best?

Each person is unique. Compared to another person with IBD, you have different genetics, a different microbiome composition, a different disease type, a different environment, and your own lifestyle and preferences. In my experience using diet as a therapy for patients with IBD, even two individuals who seem similar will respond quite differently to a given therapy. This is why each person needs an individualized option, such as my 3D-Dietary® Approach, which helps them select the appropriate dietary therapy, modify it to their specific triggers and nutritional requirement, and adapt it to fit comfortably into their daily life and treatment plan.
